[PATCH][next] staging: r8822be: fix memory leak of eeprom_map on error exit return
From: Colin King
Date: Wed Aug 23 2017 - 10:34:46 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
A memory leak of eeprom_map occurs if the call to halmac_eeprom_parser_88xx
fails. Fix this by kfree'ing it before returning.
Detected by CoverityScan, CID#1454569 ("Resource leak")
Fixes: 938a0447f094 ("staging: r8822be: Add code for halmac sub-driver")
